I'm not an expert by any means (having only played with WSUS a few times). I would ask if you have IIS installed on the server though? It seems to me that it's having problems with that portion. If you have IIS installed, does it have the ASP components installed?

Otherwise, I would suggest looking at Microsoft's support pages to see if there's a solution to this. Or wait for someone else who has more knowledge about WSUS to reply.

And also, do you have WSUS installed? I think you may need to install the base version of WSUS before you can install SP1. Or there may be a different file that you can download (which is the entire WSUS product with SP1 integrated).
